Today we will identify fractions on a number line.

A number line and a ruler are very much alike. 0 1 2

On a ruler, each inch is considered one whole inch One Inch Two Inches Three Inches Nine whole inches
5
The marks in between the whole inches are fractions of an inch ½ Inch 2 ¾ Inches 7 ¼ inches

Number lines are read the same way. The Numbers are read as whole numbers. The marks in between are read as fractions. 0 1 2
7
There are three steps to reading fractions on a number line Step One- Start on the whole number and Jump to the next whole number. That is your denominator. Step Two- Jump, starting at the first whole number. Stop at the point you are naming. This is the Numerator. 0 1 2 4

12
Mixed number fractions Step Two- Jump, starting at the first whole number. Stop at the point you are naming. This is the Numerator. 0 1 2 4 2
13
Mixed number fractions Step Three- Write the whole number as a whole number beside the fraction. 0 1 2 4 2 1
14
